When the predetermined condition is met, that is, the mobile device is in a safe zone, the mobile device operates a normal mode in operation 430 such that a user can access the mobile device. When the predetermined condition is not met in operation 420, that is, the mobile device is not in the safe zone, the mobile device requires a user to enter a password in operation 440 to authorize the user to access the mobile device.

FIG. 5 illustrates a method of selectively applying a security mode in a mobile device according to an embodiment of the present inventive concept.

A predetermined condition is set in the mobile device in operation 510. When an activation switch is selected in operations 520A or 520B, a security mode is not performed to enter a normal mode in operation 530 or the security mode is performed in operation 540 when the predetermined condition is not met in operation 510. That is, the mobile device selectively performs the security mode according to selection of an activation switch as a user input. The mobile device selectively requires a user to perform the security mode. For example, when the mobile device is in a safe zone according to the predetermined condition, the user is not required to process the security mode to enter a password. However, the mobile device is not in the safe zone according to the predetermined condition, the user is still required to process the security mode to enter a password. Here, the password may be a character, number, motion, audio, and/or image.

FIG. 6A illustrates a method of setting a condition for a safe zone in a password setting mode of a mobile device according to an embodiment of the present inventive concept

A user selects a settings menu in operation 610, and then selects a password setting menu in operation 620 to set the mobile device as a security (password setting) mode or a non-security (no-password setting) mode.

A predetermined condition for a safe zone is selected in operation 630, and then is set in operation 640.

FIG. 6B illustrates a method of setting a condition for a non-safe zone in a non-password mode of a mobile device according to an embodiment of the present inventive concept.

When a user selects a non-security (no-password setting) mode or does not set a security mode in the settings menu in operation 650, the settings menu may further include a menu to select a non-safe zone (or password-required zone) in operation 660. The predetermined condition can be set in operation 670 such that the mobile device monitors a current condition thereof to determine whether the current condition meets the predetermined condition. When the predetermined condition is met, the mobile device requires the user to enter a password to access the mobile device in the non-security mode of the mobile device. When the predetermined condition is not met, the mobile device does not require the user to enter the password in a similar manner to the non-security mode.

FIGS. 7A through 7I illustrate screens 700 a through 7I of a mobile device to set a condition for a safe zone of a security mode or a non-safe zone of a non-security mode according to an embodiment of the present inventive concept.

When a settings menu (button or icon) 710 is selected in the screen 700 a of the mobile device as a user input in FIG. 7A, the screen 700 b of FIG. 7B is displayed on a display unit and/or user input unit of the mobile device to show a selection of “security setting” 721 to set a security (password) as a security mode, a selection of “all” 722 to apply the security mode to all functions or operations of the mobile device, and a selection of a “safe zone” 723 to prevent the security mode in a predetermined condition. It is possible that the selection of “all” 722 and selection of “safe zone” 723 may be displayed in a separate screen from a screen of the security setting 721, that is, the selection of “all” 722 and selection of “safe zone” 723 may be displayed, performed, or selected independently after the security setting 721 is performed to set the security mode.

When a menu of the safe zone 723 is selected, the screen 700 c is displayed to show an area menu 731 and/or a time menu 732 as the predetermined condition. It is possible that both the area menu 731 and the time menu 732 can be selected and set as the predetermined condition. It is also possible that only one of the area menu 731 and the time menu 732 can be selected and set as the predetermined condition.

When the time menu 732 is selected, a specific time or a time period is set as the safe zone, using a new screen. Setting a specific time or a time period is well known, detail descriptions thereof will be omitted. When the time menu is performed to set the predetermined condition of the safe zone, the mobile device releases the security mode at the specific time or during the time period such that the user can access the mobile device without the security process according to the set time menu.

When the area menu 731 is selected, one or more area settings are displayed on the screen 700 d of FIG. 7D. The one or more area settings may include a WiFi selection menu 741, a Bluetooth selection menu 742, and a communication method selection menu 743.

When the WiFi menu 741 is selected, at least one WiFi network 751 can be input, detected and then displayed, or selected as a safe zone in the screen 700 e of FIG. 7E. When a user with a mobile device stays in a house of the user, for example, and an AP is located as a home use inside the house of the user, the AP as a home use may be reliable network and environment to the user and thus the home AP can be set as a safe zone. In this case, the user does not have to enter a password every time to activate or access the mobile device within an accessible area of the AP and/or inside the house. However, when a user with a mobile device stays away from the AP, the mobile device requires the user to enter the password since the predetermined condition is not met or the mobile device cannot communicate with the AP or lost a signal from the AP.

When the Bluetooth (device) is selected, at least one device 761 can be input, detected and then displayed, or selected as a safe zone in the screen 700 f of FIG. 7F. When a user with a mobile device is in a vehicle owned by the user, for example, the Bluetooth and/or the vehicle may be reliable network and environment to the user and thus the device can be set as a safe zone. In this case, the user does not have to enter a password every time to activate or access the mobile device within an access area of the device, that is, within an inside of the vehicle.

It is possible that when a user vehicle is set as the device or the AP for the safe zone and when a signal indicating an emergence, for example, traffic collision or accident to the vehicle, is generated from the vehicle and then transmitted to the mobile device through the Bluetooth or WiFi, the mobile device can recognize the received signal as a predetermined condition of a safe zone so that the user can access and/or use the mobile device without entering a password in the security mode of the mobile device. Here, the vehicle and the mobile device are configured to recognize the signal as a portion of the predetermined condition of a safe zone. In this case, a combination of the selected device and a specific or predetermined signal from the selected device can be set as the safe zone of the mobile device, and when the mobile device receives the signal from the device, so that the user can access or use the mobile device without performing a security check process in a security mode of the mobile device.

It is also possible that when a user medical device is set as the device or the AP for the safe zone and when a signal indicating an emergence for example, a life threatening situation or accident to the user, is generated from the medical device and then transmitted to the mobile device through the Bluetooth or WIFi, the mobile device can recognize the received signal as a predetermined condition of a safe zone so that the user can access and/or use the mobile device without entering a password in the security mode of the mobile device. Here, the medical device and the mobile device are configured to recognize the signal as a portion of the predetermined condition of safe zone. In this case, a combination of the selected device and a specific or predetermined signal from the selected device can be set as a predetermined condition of the safe zone of the mobile device, and when the mobile device receives the signal from the device, so that the user can access or use the mobile device without performing a security check process in a security mode of the mobile device.

When the communication method 743 is selected, one or more communication methods (CMs) 771 and 772 can be selected and set as a safe zone on the screen 700 g of FIG. 7G. In this case, a carrier name 771 and/or telephone number 772 can be reliable to the user. That is, when the user communicates with the person of the telephone number and the carrier name, the user does not have to enter a password to use the mobile device.

In the screen 700 h of FIG. 7H, at least one or a combination of the Wifi, Bluetooth, and communication method can be selected and/or set in a menu 781 as safe zone.

When the security mode is not selected or set in the settings menu 710 of the screen 700 a, a menu 791 of a non-safe zone can be selected and set such that the mobile device is set to perform a security mode in a non-security mode of the mobile device. For example, an AP, a device, or a communication method is set as the non-safe zone using one or more non-safe zone selection processes similar to the safe zone selection processes of FIGS. 7D through 7H.
